Change the default 'rhizome.datastore_path' to "rhizome", ie, a sub-
directory of the instance directory.
Add a new erename() operation to "os.h".
Clean up the code around the fix 39f582cca (two commits ago) for a bug
introduced in 2014: the 'rhizome.db' file was always being created in
the instance directory, regardless of the setting of the
'rhizome.datastore_path' config option.
Whenever the Rhizome database is opened (by the server or by a CLI
invocation), if the database file does not exist but there is a
'rhizome.db' file in the legacy location, then move that file (and any
accompanying "blob" and "hash" sub-directories) to the configured
location.
Update copyright notices.
Recent addition of the GCC __attribute__(alloc_size) to some functions
in mem.h broke the build when using Clang 3.5. This commit introduces
configure-time checks for all GCC attributes used in the Serval source
code, and adapts accordingly.
If no instance directory specified, then use paths like
/etc/serval/serval.conf
/var/cache/serval
/var/log/serval
/var/run/serval
etc. for files, instead of all in a single directory.
Log all directory creation as INFO messages.
Interpretation of log.file.directory_path has changed slightly.
Updated servald configuration tech doc.
